Naturally made clay, such as pottery clay, that has air-dried has the ability to be rejuvenated by adding water. Plastic clays that have air-dried do not have the same ability. Once the moisture is evaporated from the clay, the plastic molecules will not re-absorb moisture. Processing air-dried pottery clay is an easy task known as reconstitution. The water-soaked clay is called slurry. Excess moisture is pulled from the slurry using a plaster bat.

Things You'll Need

  • Plastic container with lid
  • Water
  • Air-dried pottery clay
  • Wooden spoon
  • 2-inch thick, 10-inch square plaster bat

Break the air-dried pottery clay into pieces. Put the broken pieces in a plastic container.

Fill the container with water until the water level is 1/2 inch above the air-dried pieces.

Place the lid on the container. Allow the container to sit for 24 hours.

Open the lid. Stir the clay and water together into a slurry. Leave the lid off the clay and let it sit for 24 hours.

Place a 2-inch thick plaster bat on a flat work surface. Slide or lift the bucket with the water and clay mixture and place it on the floor by the edge of the flat work surface.

Stir the clay and water mixture. Reach into the bucket and dip your hand into the wet clay. Scoop a handful of wet clay up from the bucket and place it on the 2-inch plaster bat. Repeat the process until the surface of the plaster bat is covered.

Allow the wet clay to dry on the plaster bat until you touch the top of the clay and it does not stick to your finger. Immediately put the clay in an air tight container for storage.
